@Ntthfi STATES THOMAS A. MAB/TIN, OF FERGUS FALLS, MINNESOTA.

COLLAR BUTTON.

Application filed April 21, 1922. Serial No. 555,927.

T 0 all to 710m it may concern Be it known that I, THOMAS A. lv'iARTIN, a citizen of the United States, residing at Fergus Falls, in the county of Otter Tail and State of Minnesota, have invented certain new and useful Improvements in Collar Buttons, of which the following is a specification.

This invention relates to separable buttons, and has for one of its objects to simplify the construction and increase the efficiency and utility of devices of this character.

With these and other objects in view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claim, and in the drawings illustrative of the preferred embodiment of the invention.

Figure 1 is a side elevation of the improved button'with the parts united and partly in section.

Fig. 2 is an enlarged transverse section on the line 22 of Fig. 1. a

Fig. 3 represents the two parts of the 1111- proved button separated, and one of the parts in longitudinal section.

-The improved button comprises a base portion 10 having a shank 11 extending therefrom, the latter having an enlarged head 12 formed with a stem terminating in a globular tip 13 spaced from the head.

The attachable and detachable portion of the button comprises a. stock 14L enlarged at the ends as shown at 15 and 16.

The enlargement 16 is formed with a rela tively large socket 17 to receive the tip 13 of the base member.

At opposite sides of the socket 17, a seat 18 is formed, and the latter intersects the socket 17. The seats 18 are parallel in cross section as well as arcuate in plan. Arranged within the enlargement 16, is a pair of spaced parallel resilient clamping rods 19. The ends of the rods 19 are embedded in the enlargement 16, while the intermediate portion of each rod extends across the socket 17 and also through a seat 18. The normal po sition of the bars 19 is such that they are spaced from a portion of each seat so that when the intermediate portion thereof is pressed laterally from the socket, in a manner as hereinafter referred to, the said laterally movable portions of the bars will be shifted to engage that portion of the seats which the bars are normally free of. The distance from the rods 19 is slightly less than the diameter of the tip 13, so that as the socket 17 is forced over the tip 13, the members 19 will be distended to allow the tip to pass and then closely engage the neck of the tip by their reaction and hold the parts with sufficient force to prevent their separation under normal conditions, but which will yield and permit the separation of the parts when abnormal force is applied.

The portion 15 may be constructed of any size or of any ornamental configuration. The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that modifications within the scope of the claimed invention may be made in the construction withoutdeparting from the principle of the invention or sacrificing any of its advantages.

Having thus described the invention what is claimed as new is A separable button comprising a base member having a shank formed with a head,

provided with astem terminating in a globu lar tip, an attachable member formed with a. socket for the reception of said tip, and further provided at opposite sides of said socket with a pair of opposed seats intersected by the sides of the socket, and a pair of parallel spaced resilient bars having their ends rigidly embedded in said attachable member and each having its intermediate portion extending through the socket and a portion of a seat whereby when said bars have their intermediate portions shifted laterally by the passageof t-h'e tip. into the socket, the said intermediate shifted portions will extend against the portions of the seats they are normally free of to provide for the passage of the tip, said intermediate portions of said bars when passed by said tip acting as a means to retain the tip in the socket.

In testimony whereof, I afiix my signature hereto.

THOMAS A. MARTIN.
